COMBINED COOLING, VENTILATING, HEATING, HUMIDIFYING, AND PURIFYING-APPARATUS.

' Specification of Letters Iatent. Patented July 15, 1919.

Application filed August 24, 1916. Serial No. 116,643.

To all whom it may concern:

Be it known that I, BERNARR MACFADDEN, a citizen of the United States ofAmerica, residing in the city, county, and State of New York, haveinvented a new and useful Improvement in Combined Cooling, Ventilating.Heating, Humidifying, and Purify ing Apparatus; and I do hereby declarethe following to be a full, clear, and exact description of the same.

This invention relates to a combined cooling, ventilating, heating,humidifying and purifying apparatus.

One object of the invention is to provide an apparatus that may beusedeither for cooling in hot weather or heating in cold weather, orclearing the air of dust or other 4 impurities.

Other objects are to providean apparatus adaptable for .use under avariety of conditions and for a variety of purposes.

Still other objects will appear hereinafter.

While I describe the invention in minute detail, the invention is notlimited to these, as the details of combination and structure may begreatly varied without departing from the scope of the invention asclaimed.

In the accompanying drawings, showing, by way of example, one of manypossible embodiments of the invention Figure 1 is a longitudinalsectional view partly in elevation;

Fig. 2 is a horizontal sectional View; and

Fig. 3 is a sectional view of a detail.

The apparatus is shown as applied to a building having a wall 10 andfloors 11 and 12. the latter of which may be a basement or cellar floor.

Through the wall 10 is passed an elongated box 14 adapted to receiveoutside air at its outside end and terminating at its inner end inconduits 15 leading to the rooms to be cooled or heated.

The interior of the box contains the heating and cooling apparatus aswill be explained.

In order to insure that a suflicient current of air pass through theapparatus to the rooms, a motor driven fan 16 is installed.

If there is a breeze outside of the building the use of the fan may bedispensed with even for cooling and to this end I have provided a hood18, pivotally supported by a pin 19, in a bracket 20, and provided witha vane opposite to its normally open side 22.

If the breeze moves in any direction parallel to the Wall 10, the vane21 keeps the open side 22 headed toward the breeze which is deflectedthrough the box 14 by the balanced door 24 pivoted at 25 and carrying acounterweight 26.

If the breeze comes perpendicularly to the wall 10, the door 24 closesthe open side 22 and the air passes'through the open end 28 and thencethrough the box 14.

When the apparatus is used as a heating plant, heat is derived from ahot water heater 29 of suitable construction, the heated water passesupwardly through the pipe 30 to the coils 31, 32, the valves 34, 35, 36,37, 38 being open and the valves 40, 41, 42 being closed.

From the coils 32 the water passes through the pipes 44, 45, 46, 47, "48back to the heater 29, the valves 50, 51, 52, 53, 54 being open, thevalves 56, 57, 58, 59, 60, 61 being closed.

If desired, the valves 57 and 58 may remain wholly or partly open, inwhich case water also passes through the lower perforated pipe 63 (Fig.3) and percolates upon the curtains 64.

' The perforated pipe 63 comprises a plurality of zig-zag portions, justunder and having the general shape of the upper perforated pipe 65 shownin Fig. 2.

The pipes 63 and 65 are both of the same configuration and are each bentto form substantially parallel zig-zag sections as shown in Fig. 2.

Hanging from each zig-zag portion of the lower pipe 63 is the curtain64, secured at the bottom to a similar zig-zag rod 66 se cured to thebottom of the box 14. Thus zig-zag paths are formed between the moistureladen curtains from which water is evaporated and absorbed by the airpassing therethrough.

The curtains are provided with U-shaped cut-out portions forming flaps68 which wave in the air and serve to increase the evapor tion. v a

The expansion tank 69, connected through the valve 35 with the pipe 30serves to store any overflow from the system.

Water may be introduced into the system through the water main 70; whilethe systern may be drained through the waste pipe 72 and valve 73.

When the apparatus is used as a cooling plant, the cooling may be byiced or cold water used once, or repeatedly, by water from the watermain 70 cooled or not by ice, or by iced water and water from the main70 combined. a

Water from the main 70 is assed through the valve 71, the main pipe 47,the valve 59, cold coils 75, in the ice box 85, through the pipe 77, thevalve 40, the pipe 30 to the coils 31 and 32, the valves 73, 54, 61, 58,53, 60, 36 being closed.

From the coils 31, part of the water passes through the valve 42 andpipe 76 to the spray nozzles 80.

From the coils 32 the water passes through the valve 50 into the pipe81, and through the valve 56 into the pipe 82. Part of the water passesout through the spray nozzles.84.

From the pipe 82 water passes through the pipe 45, the valve 57 and outthrough the perforations of the pipe 63- on to the curtains 64.

The ice box 85, may contain ice for cooling the water passing throughthe coils 75. The drip from the ice may pass out through the pipes 86and 87 to the waste pipe 72, or it may pass through the valve 89 andupper perforated pipe 65 on to the curtain 64.

The coils 31 are covered with a covering of felt or other absorbingmaterial 7 0 which is kept wet from the spray nozzles 80, or they can beused without cov'ering.

The overflow from the nozzles 80 and 84,

and the pipes 63 and 65 may overflow through the pipes 87 and 72, orsome or all of it may be drawn through the pipe 90, the

, valve 91, the pump 92, the pipe 93 and the and is somewhat cooled, butnot to the dew point and the air is not saturated. Passing over the wetcovered or uncovered coils 31, the air takes up moisture therefrom byevaporation and absorption which cools the water in the coils 31. Thiscooled water passes into the coils 32, which it cools; and the aircoming in contact with these cold coils is further cooled, and all dustand impurities removed therefrom.

Next the air meets the spray from the nozzles 84 and is further cooled,washed and mixed with the spray but is not fully saturated. Thence theair comes into contact with the curtains 64, whereupon the freeparticles of water are absorbed by the curtain and held in contact withthe current of unsaturated air passing thereover, whereupon furtherevaporation and cooling take place; and the cooled air passes outthrough the conduit. Should the carrying out (if the above process beinterfered with by the air becoming saturated, obviously the amount ofWater sprayed into the air would be decreased until saturation no longertakes place.

It will be noted that the apparatus may be used in a greater variety ofways, that parts may be used in combination with other parts, be put outof action or omitted entirely. For instance, any one or several of theparts 16, 18, 29, 76, 31, 32, so, 84, 63, 65, 92, may be put out ofaction or omitted.

Many other obvious omissions, changes of structure and modifications ofprocess will suggest themselves.
